BUTTQN-FASTENER.

SPECIFICATION forming part of Letters Patent No. 302,299, dated'July 22,1884.

Application filed May 19, 1884. (No model.)

To all whom it may concern:

Be it known that I, JAMES F. THAYER, a citizen of the United States, residing at Provideuce, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in ButtonrFasteners; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to ings, and to the letters and figures of reference marked thereon, which form a part of this My present invention relates to that class of sheet-metal button-fasteners which consist of a table and penetrating-prongs, by which the said fasteners are secured to a fabric.

My present invention has for its object to provide such fasteners with a carryingprong for an eye-shank button, whereby the same is retained in position on the fabric, and the chances of the said button loosening or becoming detached being greatly diminished.

To this end my invention consists, prinrarily, of a button-fastener consisting of a table provided with attaching-prongs, one of which is bent near its junction with the said table, to form a loop for the reception of an eye-shank button, said loop being provided with shoulders for retaining the button in position after being attached to a fabric; also to equalize the To illustrate my improvements I refer to the drawings, in which Figure 1 is atop'plan View of the blank from which my improved Fig. 2 is a side elevation of same, with button in position, ready for attachment. 1

Similar letters of reference indicate like parts in the several figures.

Again referring to the drawings, A is a button-fastener formed from the blank shown in Fig. 1, consisting of the table a, having the prongs b and b integral therewith. These prongs are subsequently bent at right angles to the said table, as shown, and form the means for attachment to a fabric. The prong b, which constitutes the carrying-prong for the button, and embodies the principal feature of my invention, is bent at a near its junction l with the table a, toform a loop for the reception of an eye-shank button, said loop terminating in a penetrating-prong, and provided with the shoulders at. (Shown in the drawings.) When the prongs of the fastener are bent at right angles to the table, as shown, these shoulders are nearly on a line with the top of the table a, and stand above the fabric when attached thereto. The method of attachment to fabric is the same as is commonly used with this class of fasteners. The buttoneye, by reason of the enlarged width of the shoulders, is passed over into the loop sidevents the said eye from slipping on the prong and causing the said prong to lift up and be come disengaged from the material, thus rendering the attachment more secure than if a straight smooth prong having no shoulders were used, enabling me to furnish a cheap and efhcient fastener, easily attached, and not liable to become loose or disengaged.

The form of the end of the button-carrying prong may be changed, if desired, so long as it retains the shoulders, which are the essential features of my invention.

Having described my invention, I claim- The herein-describedbutton-fastenerA,consisting of the table or, provided with prongs b and b, the prong 6 being bent near its juncbutton-eye in said loop, arranged and adapted for use substantially as shown and described. In testimony whereof I affix my signature in the presence of two witnesses.

JAMES F. THAYER.
